drm/panel-edp: Add more panels with conservative timings

Same as commit 7c8690d8fc80 ("drm/panel-edp: Add some panels with
conservative timings"), the 3 panels added in this patch are used by
Mediatek MT8173 Chromebooks and they used to work with the downstream
v4.19 kernel without any specified delay.

These panel IDs were found from in-field reports, but their datahseets
are not available. For BOE 0x0623 and SHP 0x153a, their product names
are retrieved from the EDIDs. The EDID of AUO 0x1999 does not contain
such information, so list as "Unknown" in this patch.

Update these entries with less-conservative timings from other panels of
the same vendor.
